You There in the Back Row -- This Means You.

Student, referring to pinus: Wait, does that actually mean "penis"?
Latin teacher: No. But once I made a joke about penises in a paper in college and my teacher wrote, "never do this".
(class laughs)
Latin teacher: So guys, don't play with your penises!
